I just kind of went with the flow after college. I got into a random desk job via a temp firm in 2008. No health insurance, and a pay cut from working in a restaurant. I just focused on putting 1 foot in front of the other, living day by day. I wound up in an industry I never would have chosen, and it's actually a great fit working with engineers. I worked my way up into a more career-centric role, but I could have just as easily been laid off or fired again and had to start from the bottom in another industry. Everyone has setbacks.
My SO never went to college or military. He was smart but couldn't be bothered to try in highschool. Teachers told him he was wasted potential. But when your parent dies in front of you when you're 14, getting good grades falls off on the list of priorities. He did customer service, restaurant, and construction work for years, making crap money and struggling. He almost got car jacked in Detroit, but smashed the guy's face in with a truck door. He almost stepped off a roof once things were that bleak.
But as a hobby he's been into computers since childhood. And on a whim in his late 20s a friend gave him an opportunity to work a low-paying call center job for a MSP (Managed Service Provider). They took calls for the home shopping network type computer support. That job lead to another similar job at another MSP fixing computers on-site. It paid a bit more but still not much. He'd drive to optometrist offices, pickle factories, anywhere they sent him. Then he was laid off and it took him another year to find work. Through a friend of a friend he managed to get his resume into the right hands and get an interview. Pretty basic entry level IT helpdesk job but in a corporate environment. Pay was low but still better than the previous 2 jobs, and he was apprehensive about working in a corporate environment. It was barnyard IT and that first year was spent bringing a company from 1999 kicking and screaming into 2019 and Windows 10. The hard work paid off and he got a 20% raise. The same thing happened the next year and then a promotion and another big raise. He went from making $40k to $95k base + bonus with a manager title. Up for another raise in a month or two.
The theme seems to be to find a company that appreciates your hard work and rewards you. He found it in his 30s. I found that in my late 20s with consistent raises and bonuses. I took a $10k pay bump just starting the job. In 8.5 years, I've gone from $48k to $73k plus stock that's consistently going up. I rarely work overtime and I'm still hourly so if I need to it's worth it.
I'm not trying to brag. Things fluctuate. Some years are harder than others. Just keep trying.
